SHEET-METAL COASTER BRACE AND BEAM.

Specification of Letters Patent.

Patented June 11, 1907.

Application filed June 5,1906. Serial No. 320,903.

- citizen of the United States, residing at Ogden, in the county of Boone and'Statc of Iowa, have invented a certain new and useful Sheet-Metal Coaster Brace and Beam, of which the following is a specification.

The object of my invention is to provide a brace and beam of the class described of simple, durable and inexpensive construction made of sheet metal and so shaped as to attain a maximum strength with a minimum amount of sheet metal and it is especially designed for use in connection with small vehi cles known as coasters.

My invention consists in certain details in the construction of the brace and beam and in its arrangement and combination with a vehicle axle, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which 2 Figure 1 shows a side elevation of a coaster brace and beam with an axle therein embodying my invention. Fig. 2 shows a transverse, sectional view on the line 22 of Fig. 1. Fig. 3 shows a sectional view on the line 33 of Fig. 1. Fig. 4 shows a sectional view through the brace and beam at one end of the axle, and Fig. 5 shows a central, sectional view of one end of the brace and beam with the axle in position.

The brace and beam is formed complete of three pieces of sheet metal, two sides that are counterpart of each other and a top plate. These two sides are each formed of a single piece of sheet metal that may be cut and formed by dies. Each has a horizontal body portion with extensions at its ends inclined downwardly and outwardly. The inner margin of each side piece is flat at 10, except that near the lower end thereof is an outwardly curved portion 11 to receive an axle. The lower ends are fiat at 12 and the outer margins are flat at 13 and are provided with an outwardly bulged portion 14 in line with the part 11 adjacent to the inner margin 10 is a part 15 that inclines outwardly from the part 10. Adjacent to the parts 13 are the parts 16 which also incline outwardly from the parts 13 and between the inclined portions 15 and 16 is the fiat central portion 17 of the side. At the top of each side is an outwardly projecting flange 18. On the top oi the ilanges 18 01' both sides, is a flat top plate 19 connected with the flanges 18 by the rivets 20. In the flat central portion 17 is a rounded depression 21 for purposes hereinatter made clear. I connect the edges 10 of the two sides by the rivets 22 and I connect the edges 13 by the rivets 23. 4 The parts 12 are connected by the rivets 24 and the parts 17, above the depressions, 21 are connected by the rivets'25. These latter are long rivets, as clearly shown in Fig. 5. The axle is indicated by the reference numeral 26 and is provided with an annular groove 27 .in each end into which the depressions 21. are pressed. In this way longitudinal movement of the axle relative to the brace and beam is prevented.

In practical use, the three parts of sheet metal forming the brace and beam are stamped out in the form shown. Then the axle is placed in position and finally all of the parts are riveted together. In this way the rivets will cause the parts adjacent to the axle to firmly and immovably engage it and the depressions 21 are fixed into the grooves 27, thus preventing longitudinal movement of the axle. In this way a brace and beam is provided of light and durable construction that is firmly braced against strains to which it may be subjected.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, therefor is- 1. A brace and beam for coasters, comprising two sheet metal body portions having downwardly and outwardly inclined ends with their margins riveted together and their central portions inclined away from each other and their top edges spaced apart, a top plate riveted to said top edges and axle supporting portions formed in the lower ends of I the sides.

2. A brace and beam for coasters, com prising two sheet metal sides, each having a horizontal central portion and downwardly and outwardly inclined end portions, flat margins at the outer edges of the end portions, at the bottom of the end portions and at the under edges of each body portion, outwardly inclined portions adjacent to said flat margins, a Hat central portion between said outwardly inclinedportions, said fiat central portion extending to the top of the brace and beam, flanges at the top of each member eX- pressions and an axle passed throngh the out- IO tending horizontally away from each other, a wardly bowed portions and havlng notches flat plate riveted to the tops of these margins, outwardly bowed portions at the lower ends of the body portions to receive an axle, each of said outwardly bowed portions formed with a central depression, rivets connecting the margins of the two body portions together, rivets above and below the said detherein to receive the metal formed by said depressions.
